Perhaps you still are depressed and still dealing with it's effects. Perhaps also people make those comments out of concern and is a way for them to motivate you to get back to the way you looked? But it can seriously back fire as is the case with you.

It's all in your hands though. How you react, etc. Easier said than done when the things people say to us can really effect us and really hurt us. Words can really destroy a person. But you are not at that point? Talk to your mum and dad about how your feeling and about your appearance.
The reality is, that you can look like whatever you want. If people make comments, so be it. You just focus on yourself and your recovery.
